   Hot2000 is free, and works alright,. I would like to see the library's updated or find a proper download for one. But you can enter your own R values. Would anyone have a link for libraries?

   I also found one from an American site where you actually draw the house in 3D but I forget it's name off the top of my head. It was also free, and I believe came from a DOE website. I didn't like the set up as much so I moved on from it.
